Abstract
A laser beam alignment device which has a movable beam-deflection mirror, two motors for modifying the orientation of the mirror, two incremental coders associated with the motors, a thermoelectric detector placed between the target to be reached by the beam and the deflection mirror and able to supply voltage differences in accordance with the misalignment of the beam and an electronic processing system for controlling the motors as a function of voltage differences and pulses produced by the coders, so as to keep the beam aligned on the target.
